Raghunathan & Suresh Kumar (2003) represented both Macrothrix triserialis (Brady) and Echnisca triserialis (Brady, 1886) as separate species in their checklist which is an obvious error. Distribution. " Macrothrix triserialis -like animals occur in the tropical-subtropical belts of four continents" (Dumont et al. 2002). In India, M. triserialis s.str. may occur.Published as part of CHATTERJEE, TAPAS, KOTOV, ALEXEY A., DAMME, KAY VAN, CHANDRASEKHAR, S. V.

Valid species of the M. paulensis species group (Kotov et al., 2005). Earlier some authors placed it in the genera Echinisca Liévin, 1848 or Gurneyella Brehm, 1930 (do not mix with Guernella Richard, 1892!). Distribution. Tropics and subtropics of Africa and Asia, could be also found in Mediterranean Region of Europe (Kotov et al. 2005). Macrothrix rosea (Jurine, 1820) Indian records. Jammu & Kashmir— Akthar (1972), Raina & Vass (1993), Siraj et al. (2006, 2007), Ahangar et al. (2012a); Rajasthan — Sharma V. et al. (2008, 2012), Sharma R et al. (2011); Uttarakhand —Kumar et al. (2012). General record— Fernando & Kanduru (1984) as Echinisca rosea. Remarks. Described from Switzerland (Jurine, 1820). The M. rosea-triserialis group was recently revised (Dumont et al., 2002; Kotov et al., 2004). Probably, M. rosea is only present in the northern Palaearctic, while the southern Palaearctic is mainly occupied by M. triserialis. Most probably Fernando & Kanduru (1984) meant just the latter taxon, yet we have no chance for a final conclusion due to the absence of any descriptions and illustrations. Macrothrix shadini Mukhamediev, 1963 Indian records. General record— Fernando & Kanduru (1984) as Echinisca shadini. Remarks. Macrothrix shadini, described from Uzbekistan (Mukhamediev 1963), is a junior synonym of M. triserialis (Smirnov 1992). Most probably, just M. triserialis was recorded by Fernando & Kanduru (1984) under this name.Published as part of CHATTERJEE, TAPAS, KOTOV, ALEXEY A., DAMME, KAY VAN, CHANDRASEKHAR, S. V.

Status of Migration of Parents as a Mediating Factor of Problem Solving and Other Psychological Problems
No full textThis study investigates the impact of parental migration on the creative problem-solving abilities and psychological well-being of secondary school students in Malappuram District, Kerala. With Gulf migration being a prevalent socio-economic phenomenon in the region, the study aims to assess whether the absence of parents, particularly fathers working abroad, has a mediating influence on students\u27 cognitive and emotional development. Utilizing a normative survey method, data were collected from 185 students using standardized tools for measuring problem-solving skills and psychological problems. Statistical analysis including t-tests, Pearson’s correlation, and Cohen’s d effect size was employed.
Findings revealed a significant difference in problem-solving abilities between students of migrant and non-migrant parents, with the former showing lower performance. However, psychological problems were found to be statistically similar in both groups. A weak but significant negative correlation was identified between problem-solving and psychological problems in the overall sample and among students of non-migrant parents. No significant correlation was found for students with migrant parents. The study attributes lower problem-solving skills among children of migrants to factors such as reduced parental involvement, authoritarian household dynamics, emotional neglect, and limited school-home linkage.
This research sheds light on a critical yet underexplored area and recommends family and school-based interventions, including parental awareness programs and teacher training, to support children in migrant households. The study underscores the need for inclusive policies that address the educational and psychological needs of this vulnerable group
Significance of intra-personal intelligence and academic self-concept as predictors of metacognition
Full text linkThis paper emphasizes the importance of comprehending students' metacognition to their intra-personal intelligence and academic self-concept and their intra-personal intelligence. Metacognition is a comprehensive word that includes the structures associated with people's cognitive processes and information. Metacognition refers to an individual's awareness and understanding of their cognitive processes and ability to manage and shape them effectively. Metacognition, academic self-concept, and intrapersonal intelligence are interconnected in educational settings. Metacognition, which refers to the understanding and control of one's thinking processes, significantly influences an individual's perception of their academic abilities and overall self-concept in an academic context. Intrapersonal intelligence, also known as self-awareness and self-management, plays a crucial role in developing and applying metacognitive strategies. This, in turn, significantly impacts academic success and how individuals perceive themselves in educational settings. The authors discuss the importance of studies that examined the correlation between specific variables from Scopus and Google Scholar. A total of twenty-five studies were carefully chosen and thoroughly analyzed. There is a need to explore students' metacognition, specifically focusing on their intra-personal intelligence and academic self-concept as determinants

No full textEulimnadia chaperi (Simon, 1886) Fig. 5 (A–C) Fig.6 (A, D, G) Limnadia chaperi Simon, 1886; Rabet, 2010 (pg.) Eulimnadia compressa Daday, 1927; Rogers & Padhye, 2015 Material examined. MNHN-IU-2007-595 (= MNHN-Bp 326): Four hermaphrodites studied (2 complete specimens; two with a few body parts missing) Locality. Vajra Korau (Vajrakarur, Andhra Pradesh, India) (wrongly reported as ' Karnataka' in Rabet (2010)) Description. Hermaphrodite. Head broadly rectangular with marked anteroventral notch; ocular tubercle prominent; compound eye about 0.8 times the size of ocular tubercle; ocellus not visible; rostrum short, acute, rostral tip upturned; dorsal organ pedunculate, about thrice as long as broad at the base and as high as the ocular tubercle (Fig. 5 A & B) First antenna not clearly seen in the specimens Second antenna peduncle cylindrical lined with long and fine setae; antennal exopod and endopod with 8 flagellomeres, each flagellomere elongated and rectangular in shape with 4–6 spines lined on the anterior side and with a row of plumose setae arranged on posterior side. (Fig. 5 B) Carapace transparent and oval, faint yellow in coloration; carapace surface smooth; dorsal margin smooth; maximum height at about one third distance from the anterior region of the carapace; ventral margin evenly convex and smooth, umbone absent (Fig.5 A); carapace growth lines indistinct and at the margin. Eighteen to twenty pairs of thoracopods, all similar in structure and reducing in size posteriorly (Fig.5 A). Abdomen. Dorsal armature as a group of 4–8 long setiferous setae of varying length; size and number of setae diminishes towards the posterior end. Telson rectangular in shape; dorsal margin lined with 13–15 spines of similar length, spines of distal 2/3rd straight while the rest (near the mound) slightly re-curved, distalmost pair of spines at least three times longer than spines on dorsum and serrated on its dorsal margin; caudal filaments attached in between 3rd and 5th spines on a low convex mound; prominent spiniform projection present ventrally at the cercopod base and half its length (Fig.5 C). Cercopods completely broken in one specimen, half broken in other and apex broken in other; about 9–10 setiferous setae on the basal half (till the small spine), setae as long as the distal most spine of telson, small spine present immediately posterior to these setae about as long as the width of the cercopod at the point of attachment, (Fig. 5 C). Eggs. Rabet (2010) examined the egg morphology of the same specimens in detail (See table 1) (Fig. 6 A). Internal structure of egg shell consisting in a heterogeneous layer with large vesicle in the middle and smaller vesicle in the internal and in the external part. Larger vesicles are localized under the crest (Fig. 6 D & G). Size. Length: 5.8–6.1 mm; height: 3.4–3.6 mm. Remarks. The Indian population from Vajrakarur was described as E. chaperi by Simon in 1886 and synonymized to E. compressa Baird by Daday (1927) using Simon's collection, but, without any comparison with the Baird's types. Under this name Daday identified one more population from Cambodia (see later E. magdalenensis). Both populations have spherical eggs ornamented with polygons which could have been indiscernible during Daday's time. Eulimnadia chaperi egg is distinctly marked with very narrow furrows of various shapes at the base of every polygon while the polygon base in Cambodian population is smooth; the internal egg structure of both populations is also clearly different (Table 1; Fig.6 A, D, G and B, E, H). Given the distinct differences in the egg morphology, we do not support the synonymy of E. chaperi types with E. compressa (Daday, 1927; Rogers & Padhye, 2015) and re-instate its species status. The diagnostic characters of egg surface of E. chaperi also closely match with the recently described Indian species, E. azisi Babu and Nandan, 2010 from Kerala, South India (Babu & Nandan, 2010). The number of polygons and presence of very small and narrow furrows at the base of each polygon in these two species are very similar. Eulimnadia azisi could thus be a junior synonym of E. chaperi but this can only be confirmed by studying the types of the former species.Published as part of Padhye, Sameer M. & Rabet, Nicolas, 2017, Re-description of two spiny clam shrimps (Crustacea: Branchiopoda: Spinicaudata) of the Indian subcontinent from Daday de Dees's collection at MNHN with new insights on the validity of Eulimnadia compressa (Baird, 1860) and Eulimnadia chaperi (Simon, 1886), pp. 349-360 in Zootaxa 4294 (3) on pages 355-357, DOI: 10.11646/zootaxa.4294.3.5, http://zenodo.org/record/83269

Milestones in the Historical Development of Early Childhood Education in India
No full textEarly Childhood Development (ECD) is a sensitive phase in human growth that determines a child\u27s future learning, behaviour, and health. This paper analyses the importance of ECD, especially in the Indian context, focusing on historical developments, key milestones, current frameworks, challenges in implementation, and ongoing efforts to improve ECD services. The findings underscore that investment in quality ECD must be made so that more children, particularly those from less privileged backgrounds, have opportunities to access the same. Last, there is a discussion on who plays what role in shaping effective ECD practices, such as government initiatives and NGOs

The Indian record needs to be checked, probably, they belong to M. vietnamensis Silva-Briano, Dieu & Dumont, 1999. Raghunathan & Suresh Kumar (2003) listed Macrothrix laticornis (Fischer) in their checklist, but the author was represented in the wrong way. Distribution. M. laticornis s.str. is "reliably known from most of Europe, and extending east across most of temperate Asia, with outlying populations occurring as far as Central Nepal " (Silva-Briano et al. 1999).

Leptestheria nobilis
No full textLeptestheria nobilis (Sars, 1900) (Figs. 8, 9) Leptestheriella nobilis (Padhye et al. 2011) Material studied. Four females and three males from University of Pune Pond (UoP pond) (18˚33′17.62″ N & 73˚49′26.80″ E), Pune collected in June 2010 (collected by SMP). Redescription. Male. Head. Broadly rectangular; eyes moderately sized, ocular tubercle conspicuous, shape of ocellus varying but mostly triangular; rostrum dilated and spatulate; occipital condyle prolonged and projecting posteriorly; L/W ratio ~0.9–1.0 with a pointed apex; sharp stout spine present at the tip of rostrum, thrice as long as wide and arched (Fig.9A) First antenna. Long & bulbous, twice the length of the base of second antenna; about 5–8 lobes, each lobe lined with several sensillae. Second antenna. Bi-ramous with varying number of antennomeres, each antennomere bearing spiniform projections (5–8) anteriorly; spines long, slender with an acute tip; plumose setae on opposite sides (Fig. 8B) Carapace. Length. 6.7 ± 0.7 mm; Height. 3.6 ± 0.40 mm. Oblong, broadly rectangular, dorsal and anterior margin straight, umbone prominence varying between populations (prominent in ‘tableland’ specimens but not in UoP pond), number of growth lines highly varying, 10–20 easily visible, dark brown or pinkish in coloration when alive. Trunk. Consists of 23–25 segments, each with a pair of thoracopods and decreasing in size posteriorly. First two thoracopods modified into claspers (Fig. 8A). Thoracopods I & II. Broad, anterior portion of movable finger (endopod) wide but tapering and strongly arching distally (hooklike), apex of which is lined with numerous scales in both the claspers; large palp (endite 5) two segmented, nearly equal in length in the first clasper, distal segment 1.2 times in length than proximal segment in the second clasper; small palp (endite 4 outgrowth) cylindrical, ~2.5 times as long as the width of its base; palm (endite 4) roughly rectangular and projecting obtusely, a medial triangular protrusion observed at base of palm in both claspers gripping area of palm lined with spines which increase in size posteriorly. Other thoracopods having similar structure with 5 endites, an endopodite with digitiform lobes on the exopodites, decreasing in size posteriorly, the last 5–8 very small (Fig. 8C). Each of the 8–23 segments has a group of short, posteriorly directed setae with acute apices, the number first increases, and then gradually decreases, a maximum of 7–8 setae per segment is observed. Telson. Broadly rectangular in outline, dorsal margin arched; the postero-lateral edge ending with a big spine, nearly half the length of the cercopod, curved, without any serration; dorsal margin lined with 30–40 spines, unequal in size and bearing serrations; telson terminal setae originating before the telson spines (Fig. 9C) Cercopods. Long and stout, about 0.8–0.9 the length of telson, straight, gradually narrowing to an acute slightly upturned apex; tip reaching the postero-lateral projection of the telson; eighty percent of the dorsal margin lined with small similar sized serrated spinules about 30–45 in number (Fig. 9C). Redescription. Female. Similar to male morphology but with some variations. Rostrum triangular in shape, L/ W ratio of ~ 1.0 (Fig. 9B). Ninth and 10th thoracopods modified with extended epipodites for carrying eggs. Telson dorsal margin more gently arched than male and lined with 30–40 spines on the dorsal margin (Fig.9B), cercopod morphology as in male (Fig. 8D) Carapace. Length 6.2 mm ± 0.4 mm; height 4 mm ± 0.3 mm. Egg. Spherical and with no ornamentation (Figs.4C & D in Padhye et al, 2016) Remarks. The morphology of Leptestheria nobilis is highly variable (Simhachalam & Timms, 2012), although some of the characters observed in these populations, such as the shape of the occipital condyle and the structure of the cercopod, coincide with previous and original descriptions (Daday, 1923; Sars, 1900). Leptestheria dumonti Subash Babu & Bijoy Nandan, 2010 and Leptestheria simhadrii (Simhachalam & Timms, 2012) are very similar to L. nobilis in terms of their morphology and thus their species validity needs to be checked using integrative approaches. The studied population could also represent a distinct cryptic species, though, this cannot be confirmed unless topotypic information is obtained. This species was found in assemblages (see Padhye & Dahanukar, 2015 for all combinations of assemblages) or occurred alone.Published as part of Padhye, Sameer M., Kulkarni, Mihir R., Pagni, Marco & Rabet, Nicolas, 2023, New leptestherid clam shrimps (Pancrustacea: Branchiopoda: Spinicaudata Leptestheriidae) from peninsular India, pp. 205-220 in Zootaxa 5264 (2) on pages 213-216, DOI: 10.11646/zootaxa.5264.2.3, http://zenodo.org/record/783643
